SPECIFICATION forming partof Letters Patent No. 402,216, dated April 30,1889. Application iiled February 18, 188I Serial No. 300,327. (Nomodel.)

T all whom it may concern:

Be it known that I, PERRY YARR1NGTo.\',of Boston, in the county ofSuffolk, State of Massachusetts, have invented a certain new and usefulVImprovement in Apparatus for the Manufacture of Hydrogen Gas, of whichthe following is a `description Vsufficiently full, clear, and exact toenable any person skilled appertains to make and use the same, referencebeing hadto the accompanying drawing,

forming part of this specification, in which the figure in the drawingis an elevation of my improved generator7 a portion of the body or casebeing broken away and certain parts of the interior shown in verticalsection.

' My invention relates to a portable apparatus for manufacturingilluminating-gas, being especially adapted for use on railway-cars andsimilar places; and it consists in certain novel features, ashereinafter fully set forth and claimed, the object being to produce asimpler, cheaper, and more effective device of this character than isnow in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawing, A represents the body of the generator, which consistsof a metallic tank having an annular gutter, Z9, near its upper edge,the outer wall, d, of said gutter extending slightly above the edge ofthe tank. A cover, B, is provided with an annular flange, f, whichrest-s on the upper edge of the body and tightly closes it.

Resting on legs g in the bottoni of the body AA there is a metallicgas-reservoir, D, a thick wooden plate, h, being disposed on the top Q'.of said reservoir to protect it from being accidentally perforated. Adome or inverted gasometer, E, is supported by legs lo, resting on theWooden plate Zt Within the body A. On the outer side ofthe dome E, inits upper portion, are formed a series of downwardly-inclined annularflan ges, Z, which serve as guards to prevent the. liquid surroundingsaid dome from risingwhen the apparatus is subject to sudden shocks. vThe dome Yis held in position by rods m, secured thereto and to the bodyA. A verticallyarranged pipe, H, projects centrally through the Woodenplate h and reservoir-top i, said pipe having a flaring mouth,p, openingunder the topq of the dome. A pan, K, provided with perforations t inits body, is disposed within the dome E, and supported by legs fv,resting on the' plate l h. A vertical sleeve, w, is formed centrallyinthe pan K, through which the pipe H passes. Inclined annular guard-flanges 5c are formed on the side of the pan K, said flanges serving toprevent the liquid in the tank from iiowing over the top of the pan. Avertical tube, z, leads from the reservoir D between the dome and thetank, said tube openin g outward through the side of the tank, andprovided with a valve and coupling, l5, to which a gas-pipe may beattached. Handles 16 are secured to the body A, and near the lower endof said body is disposed a faucet, 17, for drawing off waste liquid.

the tank A filled with a weak solution of sulphuric acid and water belowthe flanges Z. The acid solution, passing through the perforations inthe pan K, acts upon the iron therein and generates hydrogen andcarbonio-acid gas, which passes through the pipe H into the reservoir D,where it comes into contact with the carbureting substance therein andreceives its illuminating properties. The gas as thus prepared mayreadily be withdrawn for use from the reservoir by the tube Z. Byemploying the thick wooden 4guard Zt the reservoir is protected fromaccidental perforation, which would permit the acid solution to come incontact with the carbonaceous material.

It will be seen that the apparatus described is particularly welladapted for use on rail- Way-cars and similar places where it may besubject to constant jarring, the flanges 0c preventing the acid solutinfrom overflowing the pan K and coming into Contact with the contentsthereof in large quantities, whereby the gas would be generated toorapidly. The guards Z serve a similar purpose in preventing the solutionfrom being spilled from the tank should the cover B be accidentallyremoved.

Moreover, in my improvement the reservoir D, containing the earbonaeeousmaterials, which are ordinarily of a highly-inflammable nature, is atall times completely submerged in a fireextinefuishing,` liquid, thusrendering the device far safer to transport than apparatus of this classas ordinarily Constructed.

I'Iaving,` thus explained my invention, what I claim isl. In ahydrogen-gas generator, the oom bination of a body or tank, a carburetordisposed therein and provided on its top with a guard-plate, aperforated pan for the gas-gen erating material, supported. on saidplate and provided with guard-anges, a bell or inner casing supported onsaid plate and inclosing said pan, a pipe from the carburetor openinginto said bell, and a supply-tube leading from said carburetor throughsaid body, substan` ti ally as described.

i?. In a gas-generator, the combination of a body, a reservoir foroarbureting lnaterial so disposed in said body that it may be surroundedby the aoid liquid, a Wooden guardplate on said reservoir, a perforatedpan supported on said plate and lprovided with guardanges, a bellsupported on said plate and inolosing said pan, said bell havingguardlanges, a pipe from the reservoir opening into the bell above saidpan, and a supplytube leadingY from the reservoir through said body,substantially as described.

In a gas-generator, a body provided with a gutter near its mouth, aeover for said body, a carburetor disposed in the bottom of the body, awooden guard-plate on said carb uretor, a perforated pan provided withguard-flanges supported on said plate, a bell nolosing said pan andresting' on said plate, guard-flanges on said bell, a pipe from thecarburetor opening into the bell above said pan, and a supply-tubeleading from said carb u retor thro u gh the body-wall, substantially asdescribed PERRY YARRlNG'lON,
